His official name is
"Yog-Sothoth, The Lurker at the Threshold, The Key and the Gate, The Beyond One, Opener of the Way, The All-in-One and the One-in-All"
But i call him "Yog" for short.
You'd be amazed at how simple my setup is. He's in a 1-1/2-foot tank, with a sand bottom and a large rock with a natural groove in the bottom that he uses for a tunnel (along with is own extra excavations). I only have a small "Eheim 2010 Pickup" internal filter in there and a dodgy old fluorescent light on top.
The major feature that i have is a 100 meter walk to the beach i caught and such, the ability to change 50% of his water, as often as i want, usually every 3 days. And it's the water he was living in, so perfect for him.
I do the same with my 3 foot tank, which is also stocked with fish, corals and inverts caught at the same beach.
I siphon the water in an out to avoid touching it in case of water bound toxins but i assume if it was that bad, the 3 shrimp and the Goby might warn me first
. Still i take no chances.
Oh and on the subject of safety, i do not wear the gloves i mentioned before to handle him! I do not handle him. I use a hand net to catch him, put him in holding tank and so forth. I only rely on the rubber gloves to keep contact with water to zero when cleaning.
He eats a lot, only seems to like crabs (of all sorts that I've put in there, haven't tried hermits yet), but when he's real hungry he has started recently to get excited and try to grab some fish flakes when i feed the Goby and Shrimps. I feed him a crab about half the size of him about every two days, but am pretty sure he would eat one every day. He has taken down crabs with very large claws, and one crab that was about twice the size of him (although he was nervous about that one at first, as in, it took him about 2 minutes to jump it) lol
That's about all the info i can offer. Anything else?
Edit: And no sadly no predictions yet.
